What Is A High-Fiber Diet?

Today, weight loss is at the top of the public health agenda. Dieters spend a lot of time and money to get rid of those extra inches around their waists. Yes, there are many methods to reach your fitness goals, but not all of them are safe or can bring health benefits. That is why when you want to pick a dietary plan, it is critical to think about whether it is beneficial to your health and body. If you think there is no such diet, this article is going to be an eye-opener for you. Here you will find all you need to know about high-fiber diet – an eating pattern that will not only help you lose weight, but will also help maintain a healthy digestive system.

First, it is important to figure out what fiber is. You probably know that such nutrients as protein, fat and carbs are broken down and absorbed by your body. Dietary fiber is an essential nutrient, that includes parts of plant-based foods that your body doesn’t absorb or digest. However, the fact that dietary fiber isn’t used by your body as fuel, doesn’t make it less important (12, 15, 27).

Types Of Fiber

Basically, there are three types of fiber:

  • Soluble fiber is a type of dietary fiber that dissolves in water. It can help your body lower blood cholesterol and glucose levels. It can be found in legumes, oats, barley, most root veggies, citrus fruits, apples, carrots, broccoli and more. 
  • Insoluble fiber doesn’t dissolve in water, it increases stool bulk and improves bowel movement and digestion in general. It can be helpful for people who suffer from irregular stools or constipation. This type of dietary fiber can be found in whole-wheat flour, nuts and seeds, green veggies (cauliflower, green beans, zucchini, celery), potatoes and more. 
  • This type of fiber is relatively recently discovered and is called prebiotic soluble fiber (also known as inulin). It may improve digestion, promote weight loss, relieve constipation, improve bone health and even help to control diabetes. It can be found in chicory roots, asparagus, garlic, onion, wheat, barley and more.  

So, everything is quite simple – high-fiber diet is an eating pattern that includes high amounts of foods with high content of fiber. As a rule, such a meal plan includes foods such as fruits, vegetables, whole grains, nuts, seeds and more.

Benefits Of A High-Fiber Diet

So, why is a high-fiber diet important? As it was mentioned above, this diet doesn’t only help you lose weight, but is also beneficial for your health. High-fiber diet can offer a bunch of benefits for your body (12, 15):

  • Helps To Support Bowel Health

Dietary fiber is essential for the health of your bowel. First, it softens your stool and increases its size and weight. This nutrient also makes your stool pattern more regular. It also significantly decreases your risks of such issues as constipation, diverticulosis and hemorrhoids. A high-fiber diet also helps people with watery and loose stool. 

  • Promotes Blood Sugar Control

Nowadays, diabetes is one of the most widespread and dangerous chronic diseases in the world. For instance, in 2018, 34.2 million Americans (or approximately 10.5% of the population) had diabetes. What’s more, every year 1.5 million Americans are diagnosed with this disease (25).

Of course, people with diabetes are treated with medications, but proper nutrition can be helpful as well. Fiber – particularly soluble types – can help to improve blood sugar levels and slow down absorption of sugar by your body. If your diet includes soluble types of fiber, you’ll significantly decrease your risks of type II diabetes.

  • Lowers Cholesterol Levels

When consumed on a regular basis, soluble type of fiber can help lower cholesterol levels in your blood. A high-fiber diet can also offer other benefits for your cardiovascular health, such as lowered blood pressure and inflammation. So, just add some flaxseeds, beans and oats to your daily menu to support your heart health. 

  • Improves Function Of The Colon

High-fiber diet may reduce the risks of colon cancer and make the bacterial composition more balanced.

High-Fiber Diet For Weight Loss: Is It Effective?

Foods with high fiber content tend to be lower in calories than other foods. Such foods are usually also more filling. That is why you will feel full longer and will be likely to eat less. Such a diet can be classified as low-calorie and low fat, as it limits animal-based products. That’s why such a dietary pattern can help you to solve the issue of excess weight. However, it is important to talk to your doctor or dietitian before you start sticking to this eating pattern, in order to avoid health issues and nutrient deficiencies (12, 13, 15).

What Is A Recommended Daily Intake Of Fiber?

According to the Academy of Nutrition and Dietetics, adult men should consume 38 grams of fiber per day, adult women – 25 grams per day. After reaching the age of 50 a recommended fiber intake is lower – 21 grams for women and 30 grams for men. Pregnant and lactating women should consume more fiber – at least 28 grams a day (16).

Are There Any Risks Of A High-Fiber Diet?

Although dietary fiber can be classified as an essential nutrient and is vital for the proper functioning of your body, there are still some risks. If you consume too much fiber, which is usually above 70g/day (14), you may face a number of side effects. They include nausea, stomach cramps, gas, bloating and more. That’s why it is so critical to talk to your doctor or dietitian before starting a diet. There are several tips that will help you to avoid these unwanted issues. For instance, drinking plenty of water will be really helpful in this case. It is also critical to incorporate high-fiber foods to your meal plan gradually, so that you don’t send your digestive system into a tizzy (16).
